## Curriculum

*Wave III Education Data Users’ Guides*

The Curriculum component of AHAA provides fine-grained indicators of probable curriculum exposure in math and science courses taken by AHAA participants. The textbook coding is based on curriculum frameworks developed for the Third International Math and Science Study (TIMSS) and is used to create summary measures for the topics covered (content) and the types of tasks students are asked to do with specific topical information (performance expectations). These indicators are based on detailed coding of textbooks schools reported using in each course in these two subjects. These measures can be linked to students’ academic performance, attainment, and to their health-related attitudes and behaviors as reported in the Add Health surveys. Because these curriculum measures were created independent of course titles and school catalog descriptions, comparisons can be made of curricular content and quality across students’ courses in math and/or science for a given year or overall during high school.
